Protests have flared in the United States after police shot and killed a 27-year-old Black man on a Philadelphia street after yelling at him to drop his knife.
The shooting occurred on Monday afternoon as officers responded to a report of a person with a weapon, police said.
The man has been identified as Walter Wallace.
Both officers then fired several times
One of the officers then put him in a police vehicle and drove him to a hospital, where he was pronounced dead shirtly afterwards..
Chief Inspector Frank Vanore said he could confirm that police received a call about a man screaming and that he was armed with a knife.
The two officers each fired at least seven rounds — at least 14 total shots — but could not say how many times Wallace was struck.
More than a dozen people were arrested and more than 30 officers injured in the protests, Philadelphia police said on Tuesday.
